最新研究进展:CCL11(也称为Eotaxin-1)是一种由多种细胞产生的蛋白质,如巨噬细胞和淋巴细胞。它被认为在哮喘、过敏性鼻炎和皮肤炎症等过敏性疾病的发展中起着重要作用。最近的研究表明,CCL11在阿尔茨海默病的发病机制中也扮演了一定的角色。
-
功能:In response to the presence of allergens, this protein directly promotes the accumulation of eosinophils, a prominent feature of allergic inflammatory reactions. Binds to CCR3.
